Both are getting some head work. This will be my first mx5 head attempt although I've done others.
I'll give a quick list of what we are planning on doing.
1, Georges Orange track car. 1.8 mk1
40 thou head skim. Simple porting to match up inlet and exhaust manifolds. removal of casting marks and anything obvious that might limit flow.
Exhaust intake cam swap ( run 2 exhaust cams)
Skuzzle chipped ECU
De cat
Cold Air intake
K&N Pannel filter inside standard air filter box.
14-16 deg timing mod
2, Brothers green road/track 1.8 mk1
Same again for the head, 40 thou head skim. Simple porting to match inlet and exhaust manifolds to the head. Removal of casting marks and anything obvious that might limit flow.
Swap Time. This one has two exhaust cams and the Skuzzle ECU (kindly getting donated into georges orange car). The two cams from the orange car are getting a blink motorsport Piper cam re-grind and are going into this one.
This car is also getting a Blink Megasquirt setup for the Piper Cams (rolling road to follow)
So i'll keep posting photo's as we go along over the next month or so. Get you
and i'll keep it simple and mostly picture based.Orange car first and also the first one in my new garage at home. It's only taken a year and a half to build.
Here we go it's easy to take things appart.
Radiator out First and Air con in the bin.
Rads out and aircon is off.
Alternator belt, plug leads, coil pack, daft air horns off.
Injectors, inlet manifold off.
Timing marks
Ok some people don't do this but needs must. Need the bottom pulley off to replace the oil seal, if your doing a cam belt this doesn't need to come undone. Anyway quick way to crack the big crank bolt if you don't have a locking tool to hand. As you can see rest a breaker bar on the passenger chassis leg and give the starter a quick flick. Mostly this works but it's not an ideal way to do it.
Scratched a line in the CAS so it can easily be fitted back to the same place. Although the timing will be set with a timing light.
Cams are out
And hurray the heads off. Lucky i had a cheap socket set at home for the splined cylinder head bolts.
there is a fair bit of blowby past the cylinders by the looks. The cleaner area of piston top is where gasses blow past the rings and clean that area.
No fancy tools so far just sockets pliers and spanners at home.
My 16 year old did most of the work while i watched on drinking tea.
More to follow soon.
